I don't how and where the files are saved when you play on Steam deck.
When you're running the game on PC, you only have to delete the save and block Cloud Sync.
See here:

Thanks jorgejunior appreciate it but I need for deck. Thanks anyway

Anyone help please?

I found the answer from this person: Swagnemite779

"The path to the file is:

/home/deck/ . local/share/Steam/userdata/101092353/234080/remote/

I deleted both files there and lauched the game and got the newgame option. I then re-enabled steam cloud, got the file conflict notice for steam cloud on the game's launch page, then selected the local save option so it overwrote my old save file with the fresh one.

I know this game is notorious for not having a way to easily delete saves, but I could have never imagined how much worse it could get on steam deck"

--------------------------

I should add that on my deck the directory 101092353 had a different name. But inside tha differently named directory was the 234080 folder, i just followed the instructions and it worked! Oh and since I'll only play it on steamdeck I didn't re-enable steam cloud for this game ;)

Thanks for this. Sorry for taking so long to reply. I will be honest I don't know where to access the files. Don't know where to search for them, don't know what to even open on my deck to find where to search for any files. But I appreciate you taking the time to reply. I'll just have to accept that I can't start the game again

Just in case you see this PB's toham I managed to follow the steps and deleted the two files in 234080 and now the game doesn't open at all so I basically just ruined being able to play it in any way at all following these steps

I'm having the same issue here for Steam Deck. Have deleted the save files, but then game won't launch with Cloud Sync turned off. It will launch again if I reactivate Cloud Sync, but no New Game option still.

you just have to go to the map and start in area 1 on mission 1. I dunno why, but it just seems to be the only option. The overworld map is in the book/start menu.

Thank you. This is what I've done now. Working my way through the game

np This is still such a great game, even in 2025.

Am in the same position; so frustrating.

Found out what to do. Just delete the castlevania.profile file.
DO NOT delete the castlevania.cfg file. ITs working fine for me now.
